Hi,
We do not guarantee anyone with a definite chance for success, but we have been so far 100% successful on NIW, EB-1a, EB-1b, EB-1c and other petitions for professionals.
Your case appears to be one which we feel pretty much comfortable with and confident about. Feel free to forward your resume to me at lg@shenlaw, or my partner, Prof Shen, at js@shenlaw.com.
